Definitions
- bar and gripper transfer has great advantages because it allows the unloading of material to be carried out in a simple cycle and with optimum reliability. '' a work station before loading it without ever ceasing to positively maintain the parts in a perfectly mechanically defined position.
- the parts are carried by clamps mounted on horizontal bars which support them; these bars being themselves movable relative to the press or other machine tool.
- the bar transfers usually associated with presses, for example for stamping or cutting and carrying out the automatic handling of parts on workstations, are carried out either in bi-axis configuration, or in tri-axis configuration.
- the bars are capable of longitudinal and transverse movement and the mechanical drive elements include two separate drive outputs, one for longitudinal drive and the other for transverse training.
- the tri-axis configuration there are three separate motor outputs, the third being intended for a vertical movement of displacement of the bars.
- the invention relates to the tri-axis configuration (three axes of displacement of the bars) and it relates to a device in which the three drives (longitudinal, transverse, vertical) are produced with only two motor outputs, one of them ensuring the longitudinal drive of the bars and the other successively ensuring the horizontal transverse drive and the vertical drive of slides supporting the bars.
- the transverse drive and / or the vertical drive thus obtained can be applied not to the slides supporting the bars but to the jaws of pliers.
- the second drive output is produced in the form of a rod or element with linear movement which acts on two mechanical transmissions, the first successively causing the horizontal transverse displacement over a first part of the stroke of said element , then the locking of this displacement, the second successively causing the locking of the vertical displacement on said first part of the stroke, then the vertical displacement, said first and second transmissions being mechanically linked in position with freedom of sliding of one relative to the other.
- a transfer bar with its gripping parts 11 arranged from place to place.
- the bar 10 is driven in a longitudinal movement according to the arrows L by any suitable motor output not shown.
- the bar 10 slides in slides or slides 12 which are themselves liable to transverse (arrows T) and vertical (arrows V) displacement, the assembly constituting the so-called tri-axis configuration.
- the transverse displacement T and the vertical displacement V are obtained from a single drive output driven from any suitable mechanism, by a mechanical connection member 1 and which is constituted by an element 2 movable according to a linear trajectory with a determined stroke shown diagrammatically by the segment XYZ, part of this stroke being mechanically transformed into transverse displacement T and the other part of this stroke being mechanically transformed into vertical displacement V by the cams 3 and 4 linked to the element 2 and acting on the levers 4 and 8 via the rollers 13.
- the lever 4 is articulated at a point 14 fixed relative to the frame not shown and its end 5 carries a fork transversely driving the slide 6 connected to the slide 12.
- the profile of the cam 3 is determined so that the part XY of the stroke of the element 2 causes the lever 4 to move transversely causing the slide 12 while on the YZ part of this same stroke, the lever 4 is locked in the transverse position (area 36 of the cam 3 parallel to the movement of the item 2).
- the lever 8 is articulated at a fixed point 18 and its end 9 cooperates in a fork 19 with the end of the rod 15 carrying the sleeve 16 in which slides the slide 6.
- the rod 15 is guided in its vertical movement by the fixed sleeve 17.
- the profile of the cam 7 is determined so that the part ZY of the stroke of the element 2 causes a displacement of the lever 8 vertically driving the slide 12, while in the part YX of this stroke the lever 8 is locked in the vertical position (zone 7b of the cam 7 parallel to the movement of the element 2).
- the vertical and transverse motion transmissions are, as can be seen, interconnected in position. But this connection comprises the fork 5 in which the end 6a of the slide 6 slides vertically and the sleeve 16 in which the slide 6 is free transversely, that is to say that the transverse movement transmission comprises means allowing the free movement of the vertical transmission and vice versa.
- the element 2 causes the vertical movement by the same means as in FIG. 1, namely: cam 7, roller 13 carried by the lever 8 articulated at 18 and acting by the arm 9 on the rod vertical 15.
- the transverse movement is obtained by the rod 20 which drives the crank 21, fixed in rotation on the shaft 15, which however, can slide in the crank 21.
- the rotation of the crank 21 causes the rotation of the crank 22 which drives transversely the slide 6 by rolling the roller 23 in the groove 24 or by an intermediate link 25 as in FIG. 3.
- the parts 20, 21 are established so that the XY stroke gives a rotation of 180 ° to the shaft 15 and the crank 22 is set so that at the end of this rotation, the connecting rod 23 does with the direction of movement of the element 2 an angle close to 180 °; in this way, the stroke YZ of the element 2 causes only a slight oscillation of the axis 15, which gives a practically stationary position of the transverse slide.
- the shaft 15 turns freely at 19 at the end of the arm 9.
- the shaft 15 slides freely in the crank 21.
- the vertical movement is obtained by a cam 7 carried by a part 8a secured to the lever 8 articulated at 18 and which transmits the vertical movement to the slide 6 (not shown) by the arms 9.
- the element 2 acts on the cam 7 by the roller 13a.
- the transverse movement is obtained by a toothed sector 26 integral with the cam 3 and meshing with the shaft 15.
- the cam 3 is articulated around a fixed axis 27 and moved by the roller 13b carried by the element 2.
- the stroke XY of the element 2 and of the roller 13a causes a rotation of the toothed sector 26 which drives the crank 22, the slide 6 by the connecting rod 25.
- the fixed shaft 15 in a vertical position and free to rotate, the drive of the slide 6 being done by a rod 6a slides in the connecting rod 25. It is also possible to provide that the shaft 15 is grooved and linked to the 'vertical displacement equipment: in this case, the sector 26 slides along the shaft 15 which, for its part, swivels freely in its support.
- the element 2 carries a rack 28 which meshes with the shaft 15, which is grooved and can freely slide vertically.
- the shaft 15 carries a plate 29 which forms a crank and carries a roller 30 sliding in the groove 24 of the slide 6.
- the XY stroke thus causes the transverse movement by rotation of the shaft 15.
- the shaft 15 is mounted journalled freely on the vertical movement assembly comprising the arms 9 actuated by the levers 8.
- the levers 8 are mounted on the cylinder 31 which carries the cam 3 on which the roller 13a carried by the element 2 acts.
- the profile of the cam 3 is parallel to the movement of the element 2 on the race XY which locks the slide 6 in height while the transverse drive T operates.
- the cam 3 causes the rotation of the cylinder 31 which drives vertically the arms 9, the shaft 15, the plate 29 and the slide 6.
- roller 30 escapes from the slide 24 and the rotation of the plate 29 no longer acts on the transverse movement.
- Means may be provided for locking the slide 6 against any transverse displacement during the stroke YZ, for example the roller 32 coagulating with the circular groove 32a carried by the plate 29.
- the vertical drive V is used to make the closure of a clamp.
- the element 2 causes the transverse displacement T in a manner analogous to the preceding figures by the cam 3 articulated at 27 whose profile is such that the stroke XY causes the rotation of the crank 26 which drives the connecting rod 33 causing the transverse displacement of the slide or slide 6.
- the profile of the cam 3 is parallel to the movement of the element 2 and the transverse movement is locked.
- the element 2 further carries a cam 7 on which the roller 13a rolls. During the XY stroke, the profile of this cam is parallel to the movement of the element 2 and the movement return 34 carrying the roller 13a is locked in position.
- This movement can be used to raise the slide 6: In the example shown, it is used by a transmission, not shown (shown diagrammatically by the dashed line 47 and the movable plate 48), at the closing of an articulated jaw 35 at 36 on the slide or slide 6.
- the horizontal transverse stroke is a rotation stroke of horizontal arms; the element 2 acts on its course XY on the cam 3 by the roller 13b and causes the rotation of the part 37 around the axis 38 secured to the shaft 41, fixed in position. This rotation causes the closure (according to the arrows F) of the horizontal arms 39, 40 forming a clamp with articulated fingers (these clamps mesh with one another at 42).
- the element 2 On its course YZ, the element 2 cooperates with the cam 7, which is fixed, which causes the element 2 to pivot along its axis and consequently a lifting V of the ends of the clamps.
- the cam 7 In the part of the XY stroke, the cam 7 has a profile parallel to the movement of the element 2, which locks the lifting of the clamps 39-40. In the YZ part, the profile of the cam 3 is parallel to this same movement, which locks the clamps in the closed position.
- the control element 2 can in fact receive a total control stroke ABC of variable length, the initial point A remaining fixed, the stroke AB corresponding to the transverse movement and the stroke BC corresponding to the vertical movement being of variable length.
- This can be obtained by providing a power take-off 43 displaceable on a control lever 44 articulated at 45.
- the lever 45 is driven by the cam 46 and includes a light 47 in which the catch pin 43 slides. of movement of the element 2, this light being perpendicular to the element 2 when the lever 45 is in the start of travel position.
- the stroke B C can vary from 100% to 0% of its value, the stroke AB remaining constant.
